Precision workshop bench testing and calibration for all types of safety and relief valves using advanced test stands.
Workshop Bench Testing
PTTS provides comprehensive offline safety valve testing and calibration services at our state-of-the-art workshop facilities. This bench testing method is the gold standard for verifying valve performance when equipment is out of service.
Our workshop is equipped with advanced pneumatic and hydraulic test benches capable of handling a wide range of valve sizes and set pressures. We perform meticulous set pressure verification, seat tightness testing, and blowdown adjustments to ensure your valves operate exactly as designed.
Every valve tested in our facility undergoes a rigorous inspection and calibration process, followed by the issuance of a detailed test certificate and a tamper-evident lead seal for regulatory compliance.
Offline testing provides the most thorough evaluation of a safety valve's internal condition and its ability to relieve pressure accurately.
Comprehensive visual and dimensional inspection of all internal components during the testing process.
Fine-tuning of spring tension and ring settings to achieve exact set pressure and blowdown requirements.
Rigorous seat leakage testing performed in accordance with API 527 standards for maximum safety.
Identifying and correcting minor issues before they lead to valve failure, extending equipment service life.
Testing and calibration of all types of relief valves on advanced test stands.
Verification of opening, closing, and re-seating pressures under controlled conditions.
Testing support for valves undergoing full mechanical overhaul and repair.
Issuance of comprehensive test certificates valid for industrial and insurance audits.
Thorough cleaning of the valve followed by a detailed visual and component inspection.
Secure mounting of the valve on the test stand using appropriate adapters and seals.
Increasing test pressure until the valve "pops" to verify and adjust the set point.
Performing final seat tightness tests and sealing the valve for return to service.
Fully equipped facility with the latest valve testing technology and instrumentation.
Testing performed strictly according to ASME, API, and NBIC international standards.
